The 4G63 engine, known for its robust performance and tuning potential, is a popular choice for enthusiasts looking to build a cost-effective street car. This article will guide you through the process of upgrading your 4G63 turbo setup to achieve 350 horsepower using used parts and budget boost controllers.
Understanding the 4G63 Engine
The 4G63 is a 2.0L inline-4 engine produced by Mitsubishi. It is renowned for its durability and ability to handle significant power increases. The engine was used in various models, including the Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser, making parts readily available.
Setting Goals for Your Build
Before diving into upgrades, it’s essential to set clear goals for your build. Aiming for 350 horsepower is a realistic target for a street car, allowing for reliable performance while maintaining drivability.
Defining Your Build Strategy
Consider the following factors when defining your build strategy:
- Budget constraints
- Availability of used parts
- Intended use of the vehicle
Essential Upgrades for 350 HP
To achieve 350 horsepower, several key upgrades are necessary. Below is a list of essential components to consider:
- Turbocharger: Upgrading to a larger turbo, such as the Garrett GT2871R, can provide the necessary airflow.
- Fuel System: Upgrading fuel injectors and the fuel pump is crucial for meeting the increased fuel demands.
- Intercooler: A larger front-mount intercooler will help reduce intake temperatures, improving performance.
- Exhaust System: A high-flow exhaust system will enhance turbo efficiency and engine breathing.
- Tuning: A proper tune is essential to ensure the engine runs efficiently and safely at higher power levels.
Finding Used Parts
One of the most effective ways to keep costs down is by sourcing used parts. Here are some tips for finding quality used components:
- Check local classifieds and online marketplaces like Craigslist or Facebook Marketplace.
- Visit junkyards or salvage yards that specialize in Mitsubishi vehicles.
- Join online forums and communities dedicated to 4G63 builds for leads on used parts.
Budget Boost Controllers
Boost controllers are essential for managing turbo pressure. Here are some budget-friendly options:
- Manual Boost Controllers: Simple and effective, these allow you to adjust boost pressure easily.
- Electronic Boost Controllers: Offer more precise control but can be pricier; look for used models to save money.
Installation Tips
Proper installation of components is critical for performance and reliability. Here are some installation tips:
- Always refer to manufacturer specifications and guidelines.
- Use quality gaskets and seals to prevent leaks.
- Double-check all connections and fittings to ensure everything is secure.
Tuning Your Build
After installing your upgrades, a proper tuning session is necessary. This can be done through:
- Dyno tuning for precise adjustments and performance metrics.
- Using tuning software compatible with the 4G63 to make necessary changes to fuel maps and ignition timing.
Testing and Fine-Tuning
Once your car is tuned, it’s time for testing. Take your vehicle for a test drive to assess performance and make any necessary adjustments:
- Monitor boost levels and engine temperatures during driving.
- Check for any unusual sounds or performance issues.
Conclusion
Building a 350 horsepower 4G63 street car using used parts and budget boost controllers is an achievable goal with the right approach. By carefully selecting components, sourcing used parts, and ensuring proper installation and tuning, you can create a powerful and reliable vehicle without breaking the bank.
